Patient Data

Age: 30 years
Gender: Female

Selected images.

There is anhydramnios in both amniotic sacs. The kidneys are absent in both twins. Abdominal Doppler images confirm the absence of renal arteries. An image of the empty fetal bladder is provided here for twin B.

Case Discussion

Bilateral renal agenesis in both DCDA (dichorionic diamniotic) twins. Concordant structural anomalies are rare in twins. In this case the history of consanguinity is likely significant, as familial cases of bilateral renal agenesis are considered to have an autosomal recessive pattern of inheritance.
